    • Abstract

       

      1. Benzaldehyde and four haloid-benzaldehydes have been condensed with malonic acid, in the presence of a trace of pyridine as well as in the entire absence of any condensing agent.

      2. The yields in all cases have been excellent, in some cases almost quantitative.

      3. Chlorine and bromine have undoubtedly accelerated the condensation and increased the yields.

      4. Compared to the yields obtained by Perkin’s method, these yields are very superior, the condensations quicker and the products cleaner.
